Abstract
Description
- This application claims the benefit under 35 USC §119(a)-(d) of German Application No. 10 2006 025 455.4, filed May 30, 2006, the entirety of which is incorporated herein by reference.
- The invention relates to an attachment for agricultural harvesting machines, in particular for a field chopper for cutting, picking up and further conveying of a stalk-like goods flow, for example for corn plants, into the intake gap of the intake housing.
- These attachments are also known, in particular, under the name of corn picker heads. These are known to a person skilled in the art in various designs. The object of these attachments for field choppers consists in cutting the standing corn plants during forward travel and transporting the cut plants further in such a way that they pass into the intake region or into the intake gap of the intake housing of the field chopper. Attachments are known having a plurality of rotationally driven cutting and conveying drums which lie next to one another transversely with respect to the travel and working direction and have disk-shaped intake elements which lie on top of one another, are equipped with conveying pockets and are additionally assigned transverse conveying and deflection elements in the rear region.
- The cutting and conveying drums or cutting and conveying elements are driven by the internal combustion engine of the carrier vehicle, in a manner which starts via a mechanically driven drive train, a drive train which extends transversely with respect to the travel direction and on which the required drive moments for the cutting and conveying elements are tapped off by means of angular gear mechanisms being mounted ahead of the cutting and conveying elements. A drive of this type is known, for example, from DE19544182. If blockages occur during the continuous cutting and harvesting process, the harvesting process has to be interrupted by stopping the travel movement of the carrier vehicle and the blockage has to be eliminated by reversing the drive. DE 19653367 has disclosed a reversing drive of this type. Here, the drive of the intake rollers of the intake housing of the chopper and that of the attachment has its rotational direction reversed and is decoupled from the drive of the chopping drum in the process. It is disadvantageous here that all the cutting and conveying elements are also driven during reversing and the entire harvested goods which are situated in the attachment and in the intake housing and therefore still in front of the chopping drum are conveyed back and remain on the field as debris. Here, the greater the working width, the greater the debris which remains behind.
- It is the object of the invention to propose an attachment of the abovementioned type which counteracts the risk of blockage and, if nevertheless a blockage process approaches, to detect the latter as quickly as possible and therefore to counteract the extent of the disruption as quickly as possible, in order therefore to avoid the abovementioned formation of debris to as great an extent as possible or at least to minimize the harvesting losses which are caused by reversing operations.
- Here, the invention provides that the drive from each individual cutting and conveying element can be switched on or switched off or reversed from the driver stand in the cabin independently of the other cutting and conveying elements. Here, the cutting and conveying elements can either be assigned separate clutches which produce or interrupt the drive for the respective cutting and conveying elements with the main drive train or bring about the reversal of rotational direction, or, however, each conveying element can also be assigned a dedicated drive motor which can be actuated in such a way that the respective cutting and conveying elements can likewise be driven, taken out of operation or reversed.
- Here, the switching processes can also be effected by a central control unit of the carrier vehicle according to one or more preselectable and stored algorithms, or else can be triggered individually and selectively in a manual manner by the driver of the carrier vehicle.
- Here, for example, it is also possible, precisely during reversing, for only those cutting and conveying disks to be actuated in a targeted manner which are actually affected by the blockage, with the result that only the harvested goods which have caused the blockage are also conveyed backward. Here, it is also possible for various algorithms to be stored in the program memory of a microprocessor before reversing operations, for example so that individual cutting and conveying disks can be actuated independently of one another by themselves alone, or else two adjacent cutting and conveying disks can also be actuated by the formation of a group.
- These algorithms can then also be used, for example, for the running-up phase of the cutting and conveying disks. It is also optionally possible here for the drive of the prepressing rollers to be included during reversing or, if this proves unnecessary, also to suppress the drive by the drive of the intake and pressing rollers remaining switched off during reversing.
- The clutches are advantageously an integral constituent part of the respective branching-off gear mechanism of a cutting and conveying element and they are configured, for example, as clutches which can be actuated with power assistance, for example as a multiple disk clutch. However, other clutch configurations, such as claw clutches which engage and can disengage with a form-fitting fit, are also certainly provided for this application.
- Here, the power assistance can be of electric, hydraulic or else pneumatic nature. Here, the clutches can also be configured at the same time as overload clutches which, for example, stop the traction drive of the carrier vehicle in the event of overloading.
- If, in contrast, the rotational speed of a drive element of the associated cutting and conveying disks should drop to a predefined threshold value which is measured by measuring technology in the event of overloading, a signal is generated as a result for switching off the relevant drive of the cutting and conveying disks.
- Furthermore, the invention provides for the attachment to have a dedicated closed hydraulic system for driving the cutting and conveying disks, which hydraulic system, for example, is operatively connected on the drive side to a power take-off shaft of the carrier vehicle. It is particularly advantageous here to design the hydraulic system as a load-sensing system which is regulated as a function of the load in the closed circuit with pressure cut-off means, which load-sensing system per se comprises an inexpensive and functionally reliable overload safeguard. It is also possible here that a plurality of closed operating circuits emanate from one hydraulic pump, which reduces the costs. Here, the hydraulic drive system can advantageously be a load-sensing system which is regulated by pressure and/or conveying flow and can be used, in particular, in order to save energy.
- The detection by measuring technology and evaluation are effected from the interaction of the rotational speed and rotational direction sensors which are advantageously operatively connected directly to the corresponding drive elements or are part of the latter.
- The input variables which are detected in this way therefore represent important input variables of a job computer which, according to the invention, is part of the attachment and is advantageously incorporated into a bus system, for example into an ISO bus. The further refinement of the invention provides for this job computer also to be connected to the central controller of the carrier vehicle via a bus connection and also to be coupled to its actuating and monitoring device, with the results that the process sequence can also be displayed visually.

FIG. 3 likewise refers back toFIG. 1 , but in a different inventive refinement of the mechanicalmain drive train 15, each cutting and conveyingelement gear mechanism 12 having in each case oneclutch FIG. 3 a shows an enlarged detail fromFIG. 3 .FIG. 3 b shows the drive train according toFIG. 3 in a reversing situation. Here, for the sake of clarity,FIG. 3 c shows an enlarged detail fromFIG. 3 b. - Here, this is a corn picker head in a simplified illustration in a plan view. The rotational direction arrows 14, 14′ show the rotational directions of the conveying disks of the cutting and conveying
elements carrier vehicle 2 which is configured as an automotive field chopper, ahead of itsintake housing 8 with itsintake gap 7. - Attachments of this type are known to a person skilled in the art as exchangeable devices and corn picker heads, and they are received by a connecting device of the
carrier vehicle 2 and are drive-connected to the latter. - As an exemplary embodiment, the
attachment 1 which is shown comprises eight cutting and conveyingelements 4; 4′, 4″, 5, 5′, 5″ which are supported on amachine frame 3 such that they can rotate aboutvertical axes rotational directions elements 4; 4′, 4″, 5, 5′, 5″ which are driven about vertical axes cut the corn stalks in the vicinity of the soil, catch them in conveying pockets of the cutting and intake elements and transfer them to transverse conveyors (not shown in greater detail but known to a person skilled in the art) which then collect them in conveying channels and feed them to theintake gap 7 in a manner which is guided by said conveying channels. The cutting and conveyingelements 4; 4′, 4″, 5, 5′, 5″ and theirrotational directions - According to the invention, it is then possible to actuate each of the cutting and conveying
elements 4; 4′, 4″, 5, 5′, 5″ with regard to its drive, that is to say to drive them rotationally in a separate manner or to take them out of operation or to reverse them. The actuation takes place from the control stand 33 or driver's seat from the driver'scabin 33. This is shown in an exemplary manner using the example of reversing of the two right-hand outer (in the travel direction) cutting and conveyingelements 4′, 5″ inFIG. 2 b andFIG. 3 b, which is shown symbolically by the thicker lines of these two cutting and conveying elements. - Here, all other cutting and conveying
elements 4′, 5″ remain at a standstill, which means that they are taken out of operation, as the missing rotational direction arrows on these cutting and conveying elements which are taken out of operation also show symbolically. - In contrast, the rotational directions of the two outer cutting and conveying elements which are in the reversing state have been reversed in comparison with
FIG. 1 , which corresponds to the reversing operation. In both the examples which are shown, both inFIG. 2 b and also inFIG. 3 b, thecomplete drive train 15 remains switched on during reversing, that is to say remains in motion, which is shown by the thicker lines of the drive train. - This is made possible by the fact that the
rotational direction element 4; 4′, 4″, 5, 5′, 5″ can be changed independently of the other cutting and conveyingelements 4; 4′, 4″, 5, 5′, 5″ of theattachment 1 and therefore also by the fact that at least one cutting and conveyingelement 4; 4′, 4″, 5, 5′, 5″ can be reversed and/or taken out of operation independently of the other cutting and conveyingelements 4; 4′, 4″, 5, 5′, 5″ of theattachment 1. However, there is also provision according to the invention for it to be possible for each of the cutting and conveyingelements 4; 4′, 4″, 5, 5′, 5″ to be actuated selectively within the abovementioned context. - Here, there is provision for the cutting and conveying
elements 4; 4′, 4″, 5, 5′, 5″ to be assigned drive elements 11, as a result of the actuation of which therotational directions carrier vehicle 2. Each cutting and conveyingelement 4; 4′, 4″, 5, 5′, 5″ is assigned at least onerotational speed sensor 16 and onerotational direction sensor 17. - Here, one embodiment of the invention provides for drive elements to be arranged in series as shifting
gear mechanism 12 in themechanical drive train 15 which is arranged in therear region 10 of theattachment 1, and which tap off from the latter the required drive torque for the cutting and conveyingelements 4; 4′, 4″, 5, 5′, 5″. Theclutches - The shifting
gear mechanisms 12 are therefore run through by themain drive train 1 which extends transversely with respect to the travel and working direction F and is drive-connected to the drive motor of thecarrier vehicle 2, and the cutting and conveyingelements 4; 4′, 4″, 5, 5′, 5″ are therefore coupled to the latter on the drive side. - As a result of the fact that the
clutches shifting gear mechanism 12 interact with one another in such a way that they either close or open the drive connection to the cutting and conveyingelements 4; 4′, 4″, 5, 5′, 5″ as a result of the type of their connection. In the exemplary embodiment according toFIG. 2 , the main drive train also retains its rotational direction in the case of reversing. The rotational direction of the conveying disk of the respective cutting and conveying element is determined by which of the two clutches is drive-connected to the main drive train and which is released. If, in contrast, bothclutches shifting gear mechanism 12 are released, the drive connection of the relevant cutting and conveying element is interrupted completely and therefore taken out of operation. - In the exemplary embodiment of
FIG. 3 , each shifting gear mechanism comprises only one clutch 13, this embodiment making it necessary that the rotational direction of the main drive train is reversed for reversing purposes, that is to say is likewise inverted, as is already the case in known embodiments of themain drive train 15. Each individual drive connection to the respective cutting and conveying disks can then be produced or interrupted by switching theclutches 13 on and off, which therefore makes it possible to switch the individual cutting and conveying elements on and off selectively, both during normal operation and during reversing operation. - The operating states normal operation, standstill or reversing operation can therefore be actuated for each individual cutting and conveying
element 4; 4′, 4″, 5, 5′, 5″. Here, the clutch 13, 13′ is an integral constituent part of theshifting gear mechanism 12 and it is advantageously configured as a switchable multiple disk clutch. In the exemplary embodiments, the gear mechanisms themselves are shown as bevel gear mechanisms, which is to be considered only by way of example. They can equally be other embodiments of shifting gear mechanisms, as are known in numerous cases in drive technology. -
FIG. 4 likewise shows anattachment 1 according to the invention, but with a hydraulic drive of the cutting and conveying elements, andFIG. 5 shows an enlarged detail of the attachment according toFIG. 4 .FIG. 6 shows the complete hydraulic drive system in a simplified illustration according to the rules of hydraulic circuit plans. - As shown in
FIG. 4 , according to the invention, the main drive train can also comprise a hydraulic shaft as hydraulic drive system 23, with the result that the drive element 11 is a hydraulic motor 18 which is drive-connected to the drive motor of thecarrier vehicle 2 via ahydraulic pump hydraulic pumps 19′, 19″ with pressure cut-off means 25 as overload safeguard 21, and which is driven by the power take-off shaft of thecarrier vehicle 2 via thedrive journal 35 of acentral gear mechanism 34, configured as a gearwheel train 39. Here, bothhydraulic pumps attachment 1 which lie on both sides to the left and the right of the verticallongitudinal center plane 9 can also be actuated and reversed separately and also in groups. In the exemplary embodiment inFIG. 6 , the complete hydraulic drive system 23 is shown in simplified form, each cutting and conveyingelement elements - Here, each drive element 11 as hydraulic motor 18 is assigned an overload safeguard 21 which responds if a predefined threshold value which relates to a maximum predefined drive torque is exceeded, and can also trigger a stop function. The directional valves and the overload safeguard are advantageously configured as
pressure limiting valves 24 and are designed in such a way that they are incorporated into the data bus and therefore are present at the inputs and outputs of the job computer. A hollow profile of themachine frame 3, for example, can also serve ashydraulic tank 28. - According to the invention, each drive element 11 of the cutting and conveying disks is assigned at least one
rotational speed sensor 16 and onerotational direction sensor monitoring device 32. - According to the invention, each drive element 11 of a cutting and conveying disk is assigned a slip measuring device 22 which triggers or can trigger a stop function if a threshold value which relates to a predefined nominal rotational speed is exceeded.
- It is also possible that the instantaneous travel speed of the
carrier vehicle 2 is fed back to the load-sensing regulation within the context of power consumption regulation and/or limitation, as a result of which the travel speed is adapted automatically to the loading behavior. - Here, the job computer is situated on the
attachment 1, and it is connected to thecentral controller 30 of the carrier vehicle by means of adata bus 31, in particular via an ISO bus, and can therefore communicate with saidcentral controller 30. - As a result, the driver of the
carrier vehicle 2 has the possibility of actuating the drive elements 11 via thecentral control device 30 from his driver's seat, optionally individually or in groups. -
